Change Details

On amd64, these changes reduce the size of the compiled lookup_ge and lookup_le routines by 144 bytes and 128 bytes. A buildworld test suggests that this change speeds up lookup_le calls by 21%, and slows lookup_ge calls by 8%. original timing: 52450.199u 1452.606s 59:09.38 1518.6% 73478+3095k 121089+33120io 110807pf+0w vm.radix.le_cycles: 74538053872 vm.radix.le_calls: 341220107 le_cycles/call: 218.44566701340375 vm.radix.ge_cycles: 2167673543 vm.radix.ge_calls: 3540959 ge_cycles/call: 612.1713194081038 modified timing: 52576.115u 1449.896s 59:20.06 1517.5% 73482+3094k 121161+33086io 110797pf+0w vm.radix.le_cycles: 59049221493 vm.radix.le_calls: 341211976 le_cycles/call: 173.05729472109735 vm.radix.ge_cycles: 2347601450 vm.radix.ge_calls: 3543687 ge_cycles/call: 662.4742676201369 (/ 173.05729472109735 218.44566701340375) 0.7922212286796176 (/ 662.4742676201369 612.1713194081038) 1.0821713572936902
